The Huntington project included the conversion of an existing electrostatic precipitator (ESP) and existing ash handling system to a pulse-jet fabric filter (PJFF) with an upgraded ash handling system compatible with the PJFF conversion. The work included all necessary design, demolition, procurement, construction, erection, controls and auxiliary support equipment for a complete multi-compartment PJFF system with modified ash handling.

Burns & McDonnell performed mechanical, electrical, structural and foundation design as well as instrumentation and controls. The controls engineering consisted of integrating a new distributed control system (DCS) for the FGD with the existing plant DCS control system.

This project required a significant amount of coordination and effort among the EPC JV partners and with the owner, PacifiCorp, as much of the work was completed during scheduled outages. This project was a fast-paced, highly coordinated effort that required teamwork, persistence and a willingness to work together with PacifiCorp to ultimately make them successful and achieve a high level of environmental stewardship and a value to the customers PacifiCorp serves.
